    我们得自定义ProgressBar的样式

     

    <span style="white-space:pre">	</span><style name="self_define_ProgressBar" parent="@android:style/Widget.ProgressBar.Horizontal"> //继承了android横向的ProgressBar的样式
      	    <item name="android:indeterminateOnly">false</item>
      	    <item name="android:progressDrawable">@drawable/self_define_progress</item>
      	</style>

    <?xml version="1.0" encoding="UTF-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    
    	<item android:id="@android:id/background" >	//定义的是背景色
    		<shape>
    			<corners android:radius="5dip" />
    			<gradient android:angle="270" android:centerColor="#efefef"
    				android:centerY="0.75" android:endColor="#a3a3a3"
    				android:startColor="#c7c7c7" />
    		</shape>
    	</item>
    
    	<item android:id="@android:id/secondaryProgress">   //如果有2级进度,需要定义这一项,gradient定义的是渐变色,clip如果没有的话,进度条会充满整个Progessbar
    		<clip>
    			<shape>
    				<corners android:radius="5dip" />
    				<gradient android:angle="270" android:centerColor="#99CC99"
    					android:centerY="0.75" android:endColor="#99CC99"
    					android:startColor="#99CC99" />
    			</shape>
    		</clip>
    	</item>
    
    	<item android:id="@android:id/progress">  //这个是定义1级进度,如果1级进度比2级进度大且1级进度不透明,就可以覆盖掉2级进度
    		<clip>
    			<shape>
    				<corners android:radius="5dip" />
    				<gradient android:angle="270" android:centerColor="#4abbfd"
    					android:centerY="0.75" android:endColor="#4abbfd"
    					android:startColor="#4abbfd" />
    			</shape>
    		</clip>
    	</item>
    
    </layer-list>


     

    在代码里这样使用:

     

    	private ProgressBar mProgressBar;
    	private Task mTask = new Task();
    	private int mCount = 0;
    	private Handler mHander = new MyHandler();
    	
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		requestWindowFeature(Window.FEATURE_NO_TITLE);
    		setContentView(R.layout.activity_main);
    		mProgressBar = (ProgressBar)findViewById(R.id.progress);
    		Timer timer = new Timer();
    		timer.schedule(mTask, 1000, 1000);
    	}
    	
    	private class MyHandler extends Handler{
    
    		@Override
    		public void handleMessage(Message msg) {
    			mCount += 10;
    			mProgressBar.setProgress(mCount);
    			super.handleMessage(msg);
    		}
    	}
    	
    	private class Task extends TimerTask{
    
    		@Override
    		public void run() {
    			mHander.sendEmptyMessage(10);
    		}
    	}

     

    对于圆形并有转圈动画的进度条:shape的值(rectagle矩形,oval椭圆,line水平直线,ring环形) tpye的值:渐变的样式 liner线性渐变 radial环形渐变 sweep

     

    <?xml version="1.0" encoding="utf-8"?>
    <rotate xmlns:android="http://schemas.android.com/apk/res/android"
            android:pivotX="50%" 
    	android:pivotY="50%"
            android:fromDegrees="0" 
    	android:toDegrees="360">
            
        <shape
                android:shape="ring"<span style="font-family:verdana, ms song, 宋体, Arial, 微软雅黑, Helvetica, sans-serif;color:#666666;"><span style="font-size: 14px; line-height: 18px;">  
    </span></span>            android:innerRadiusRatio="3"
                android:thicknessRatio="8"
                android:useLevel="false">
    
            <size
                    android:width="37dip"
                    android:height="37dip"
            />
            
            <gradient
                    android:type="sweep"//type为sweep为环形转圈
                    android:useLevel="false"
                    android:startColor="#F7F7F7"
                    android:centerColor="#F7F7F7"
                    android:centerY="0.50"
                    android:endColor="#B3B4B4"
            />
            
        </shape>
        
    </rotate>
